Smartphones have become an inseparable part of modern life, revolutionizing communication, work, and entertainment. However, excessive smartphone use (ESU) has been linked to various negative consequences, including addiction-like behaviors, impaired mental health, and diminished attention spans. Recent studies suggest that smartphone-related cues can trigger neural responses similar to those seen in substance addiction, reinforcing compulsive usage patterns. Understanding the effects of smartphone restriction on cue-related neural activity can provide valuable insights into developing interventions for individuals struggling with ESU.
The Role of Cue Reactivity in Smartphone Use
Cue reactivity (CR) refers to the brain’s response to stimuli associated with a habitual or addictive behavior. In the case of smartphone use, cues may include notification sounds, phone screens lighting up, or simply seeing a smartphone in one’s environment. These cues can activate reward-related brain regions, reinforcing the compulsive urge to check the device.
Research has shown that individuals with excessive smartphone use exhibit heightened neural responses to smartphone-related cues, similar to those observed in substance addiction. This heightened sensitivity may contribute to difficulty in controlling smartphone usage, leading to a cycle of compulsive checking and craving.
Investigating Neural Activity Changes Through Smartphone Restriction
To better understand how short-term smartphone restriction influences brain activity, researchers conducted a study using functional MRI (fMRI) to measure changes in cue-related neural responses over 72 hours of smartphone abstinence. The study involved 25 young adults who were regular smartphone users.

Study Design and Methods
- Participants were instructed to refrain from using their smartphones for 72 hours.
- A cue-reactivity task was designed, where participants were exposed to images of smartphones (both active and inactive) as well as neutral objects.
- Functional MRI scans were conducted before and after the restriction period to analyze changes in brain activity.
- Psychometric assessments were used to measure craving, self-control, and emotional responses associated with smartphone use.
Key Findings: How the Brain Adapts to Smartphone Restriction
1. Reduced Activation in the Reward System
One of the most striking findings was a significant reduction in activity in the nucleus accumbens and anterior cingulate cortex after 72 hours of smartphone restriction. These brain regions are heavily involved in reward processing and habit formation.
- The nucleus accumbens is associated with motivation and reinforcement learning. High activation in this area suggests strong craving and compulsive behavior.
- The anterior cingulate cortex plays a role in decision-making and impulse control. Reduced activity here indicates that participants may have experienced less compulsion to check their smartphones.
These findings suggest that even a short break from smartphone use can lead to neuroplasticity, allowing the brain to become less reactive to smartphone-related cues.
2. Alterations in Dopamine and Serotonin-Linked Activity
Further analysis using neurotransmitter probability maps revealed that activity changes in the reward system were closely linked to dopamine and serotonin receptor probabilities.
- Dopamine is a key neurotransmitter in reward-seeking behavior and addiction.
- Serotonin is involved in mood regulation and impulse control.
The findings suggest that smartphone restriction may influence neurochemical processes that drive compulsive behaviors. This could explain why some people feel withdrawal-like symptoms, including restlessness and anxiety, when they suddenly stop using their phones.
3. Increased Engagement of the Parietal Cortex
Another notable result was the increased activity in the parietal cortex, a region associated with attentional control and sensory processing.
- This suggests that participants became more aware of their environment and less preoccupied with smartphone-related distractions.
- Heightened parietal cortex activity was correlated with reduced craving scores, indicating improved cognitive control over impulsive smartphone use.
This supports the idea that limiting smartphone use can enhance focus and attentional regulation, reducing dependency on digital devices.
4. Reduced Compulsive Checking Behavior
Behavioral assessments showed that participants experienced a significant decrease in the urge to check their smartphones over time. This aligns with the observed neural changes in reward sensitivity and impulse control.
Participants also reported improvements in:
- Sleep quality: Reduced exposure to blue light and nighttime scrolling led to better sleep patterns.
- Social interactions: Without constant phone distractions, participants engaged more with people around them.
- Mental well-being: Several individuals noted feeling less anxious and more present in their daily activities.
Implications for Smartphone Addiction and Digital Detox Strategies
The findings of this study have significant implications for individuals struggling with excessive smartphone use. While a complete break from smartphones may not be feasible for everyone, implementing digital detox strategies can help manage usage and mitigate negative effects.
1. Scheduled Smartphone Breaks
- Taking regular breaks from smartphone use, even for a few hours a day, can help reset neural responses to digital cues.
- Setting specific times for checking messages rather than responding to every notification can reduce compulsive checking.
2. Mindful Technology Use
- Practicing conscious smartphone use by turning off unnecessary notifications and using grayscale mode can help decrease reliance on digital stimuli.
- Engaging in non-digital hobbies, such as reading, exercise, or meditation, can strengthen attention control and reduce smartphone dependency.
3. Sleep Hygiene and Nighttime Restrictions
- Avoiding smartphone use one hour before bed can improve sleep quality by preventing blue light exposure.
- Using do not disturb or airplane mode at night can minimize the temptation to check notifications.
4. Awareness Campaigns and Education
- Schools, workplaces, and mental health professionals can promote awareness of the impact of excessive smartphone use on brain function.
- Implementing digital wellness programs can encourage balanced technology use.

Conclusion: How Smartphone Restriction Reshapes the Brain
The study provides compelling evidence that even a short period of smartphone restriction can lead to measurable changes in brain activity. The observed reductions in reward-related neural responses, coupled with increased attentional control, suggest that limiting smartphone use can promote cognitive flexibility, impulse control, and overall mental well-being.
As smartphone addiction continues to be a growing concern, understanding the neurological basis of cue-reactivity and digital dependency is crucial. These findings highlight the importance of incorporating healthy technology habits to ensure that smartphones remain tools for convenience rather than sources of compulsive behavior.
By making small adjustments in smartphone usage, individuals can foster better focus, improved mental clarity, and greater overall life satisfaction. So, why not start with a 72-hour break and see how your brain adapts?
People Reveal the Craziest Wills They Ever Saw
From disowning a child to secretly leaving everything to a stranger, people have written many unexpected things in their wills that are only revealed to their family members after their demise. Many times, people have used this closing act to take revenge on their loved ones.
With age, many people tend to think about what would happen to their loved ones after death. They know there’s only much they can do to support them, and with that comes the thought of writing a will. The final document decides what would happen to their assets and property after their death.

Many people write their will when they are healthy and doing fine, but others do it after the doctors tell them they don’t have much time to live. Some divide their assets into parts and leave them for their close ones, while others write something unpredictable that shocks their family.
Netizens on Reddit shared some of the craziest and most bizarre things people wrote in their wills. Many of their family members had no idea what was coming their way.
Comments have been edited for clarity and grammar.
1. The Unexpected Trust Fund

u/scarlett_pimpernel: I am a qualified solicitor. A lady wanted to create a trust fund of £100,000 for her pet fish. When I asked if it was a particular type of fish, she confirmed it was just an ordinary goldfish.
She wanted it to be fed fresh avocado daily and looked after by a local dog walker after she died. She was absolutely serious.
2. No One Knows about Her

u/scarlett_pimpernel: Another lady confessed she had a secret daughter and wanted to leave the daughter some money and photographs without the rest of her family finding out. Even her husband does not know. That will be a fun conversation when she passes away.
3. The Lucky Man

u/mommy5dearest: I worked at an attorney’s office, and a little older lady gave her house and belongings to a bus driver.
She did it because he was nice to her and would help her. We were all waiting for hell to break loose when her family found out.
Her family can contest it. I was a witness to the signing. She seemed fine and knew the answers to the questions, so she wasn’t having mental problems as far as we could tell.
4. The Interesting Clause

u/WanderCold: I was in my early twenties when I was forced to write a will because of the health insurance I got at work. I discussed it with the in-house lawyer, who approved this specific clause to be added to my will.
The clause read, “My funeral wishes are that I should be buried in a coffin which has been springloaded, such that opening the coffin would cause alarm to future archeologists.”
Then, a bunch of stuff about if this is too costly, I’d be cremated and have my ashes scattered in a specific place.
5. Don’t Forget My Horse!

u/gabberrella24: I work in probate. The oddest thing I’ve seen in a will is to euthanize their beloved horse, have it cremated, and its ashes scattered with the decedent.
Lucky for her horse, she named a horse that was already dead when she passed away, so the one she got afterward lived to see another farm.
6. A List of Strange Wills

u/PirateRobotNinjaofDe: Lots of people send their friends and family on weird errands to spread their ashes (leaving money for people to take trips and spread their ashes around the world).
Pet trusts are a fun one. People leave a whole whack of money in a trust to be used for the care of their pets during their life.
However, my favorite ever (that I obviously didn’t draft) was a lawyer who left the bulk of his estate (millions in today’s dollars) to whatever Toronto-area woman had the most children at a specific date some years later. I recall the winner had 10.
7. My Grandfather’s Wish

u/snoboreddotcom: A few hours after my grandfather’s death, my grandmother came to me with a navy-blue tie featuring pink elephants.
Ridiculous looking, but she said he wore it to intimidate people in business, as someone willing to wear such a ridiculous tie doesn’t care about what people think. That scares people. He wanted me to have it so I could do the same.
8. Different Wishes

u/ALighterShadeOfPale: I work for a lawyer who does wills. We’ve had a lady put in her will that one of her adult sons would receive his share when he visited a dentist, and the other son would get it if he lost 70lbs.
Another lady put in her will that she wanted her cats cremated with her when she died. We told her that would not happen since human and animal remains are not cremated together. So, she settled on cremated separately and joined together, then buried together.
9. The Long Will

u/ALighterShadeOfPale: Typically, wills are about ten pages long (for an average person), but a woman once wrote 56 pages.
She detailed EVERYTHING from her house to people. For example, she wrote, “wooden ladle to ____, toilet paper holder to ____, magazine basket to ____.” She did this for every single item in her house.
10. She Wanted to Be with Her Husband

u/ALighterShadeOfPale: A lady told us to put in her will that she wanted to be buried on her property next to her husband. She lived on a small rural property.
It’s totally illegal to have human remains buried there. She refused to tell us whether her husband was cremated or not and said she did not want to be cremated.
Edit: Her husband had died 5 or 6 years prior. So, it’s not as though it was 50 years ago when things like that may have been a little overlooked.
11. Some Good People

u/ALighterShadeOfPale: We had a man put in his will that his family was to go to the zoo immediately after his burial (that day). We thought that was heartwarming.
Besides that, we work with many people from a particular religion. Many people we write wills for leave at least 90% of their estates to the church instead of their families.
12. The Elvis Impersonator

u/whatshisfaceboy: I’m not a lawyer, but I have this story of my rich uncle. He would visit us when we were kids, maybe once every ten years. The last time he did, he brought us to a Denny’s.
When he died, he had no friends. Besides that, his wife died due to substance abuse, and that was because of him. He left his entire estate to an Elvis impersonator. Everything.
13. The Only Beneficiary

u/AnotherDrunkCanadian: I used to work at a bank in the estate department. I was an administrator who had to manage the files, including encroachments upon the capital, i.e., “I want to take some money out now, please.”
I had this one account – a multi-million-dollar trust for one single beneficiary – the son of the deceased. Everything about the account looked fine until I learned the child was behind his parents’ death and pleaded insanity.
He was in a mental hospital and called the bank once a year requesting $50 for commissary (to buy chips and gum).
The call was always strange. He was very polite, but the quality of the call made it sound like he was far away from the phone.
14. They Wanted to Take Revenge

u/Dr_BrOneil: Last week, I handled a matter where the parents left millions in artwork to various people and wads of cash to various charities. Meanwhile, their kids got the family cats as revenge.
It turned out they did it because the kids got them the cats to comfort the parents in their old age. The parents hated the cats, but the kids wouldn’t let them get rid of them.
15. He Wanted to Give Them Something

u/gaurddog: My great uncle’s official will stated that the contents of his outhouse would go to the City Council of a nearby town after they had tried to take his land twice to build a new water treatment plant.
He spent several years fighting eminent domain claims and wanted to give them something in return. As a joke, his kids boxed up all the books and magazines in the outhouse and dropped them off at City Hall.
16. The Man Was Clueless

u/[deleted]: I am not a lawyer but work for a will writers/trusts specialist in the UK, currently studying toward my TEP.
One of our earlier clients passed away recently. Turns out the man she left almost everything to, including the residue of her estate–which was considerable–was her regular taxi driver.
She had also named him as her executor. He had no clue. The woman named as her executor and primary beneficiary in her previous two wills, a close friend of many years, was understandably flabbergasted and contested the will.
We responded to her solicitor’s Larke v Nugus request, informed Mr. Taxi Driver (who didn’t even know our client had passed), and the will was upheld.
The friend mentioned above was left a legacy of £5,000 if I remember correctly, but her nose was clearly out of joint.
Bonus observation: It takes a lot less than £ 5,000 being up for grabs to make families turn against each other. It can get really nasty. This is one of the most startling things I’ve learned in my short time in this business.
17. Hidden Fortune

Deleted user: So, my grandma, bless her heart, lived in this old, run-down trailer for years. Dirt poor, but you wouldn’t know it by the way my husband acted.
He was like a cat on a hot tin roof, waiting for her to pass. He had this wild notion in his head that grandma was sitting on a hidden fortune and that he’d inherit a ticket to Easy Street when she kicked the bucket. Cut to the will reading day.
My husband’s practically rubbing his hands together, telling me, “Sugar, put on a smile, we’re about to be rolling in dough.” We get there, and the lawyer’s all business, asking, “Who’s the ‘husband’ there?” My guy steps up: “That’s me. Is there a problem?”
Then my jaw hitting the floor. The Lawyer: Not at all…The last will of grandma states that the grandma has a hidden fortune. However, it’s to be inherited by the husband only if he fulfills three specific conditions. Otherwise, the entire estate goes to the local animal shelter.”
First, he must live for a year in her old trailer, maintaining it without any modern upgrades or outside help. Second, he’s required to volunteer at the animal shelter every weekend for the next two years.
And finally, he must write a personal essay on the value of humility and compassion, to be read publicly at the shelter’s annual fundraiser.
My husband’s face turned from greedy anticipation to utter disbelief. Grandma sure knew how to teach a lesson from beyond the grave!
